Greenfield’s center stands about 1,250 ft above sea level. Within three miles the land runs from 940 ft to 1,410 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Limekiln Hill, about 1,400 ft, 8 miles south.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 24 mi of the line.

A raindrop that lands in Greenfield reaches the Gulf of America by way of the La Crosse and the Mississippi: about 1,730 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenfield; river miles along the main stem, rounded.
Greenfield has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 5° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 35 inches of water.
